Application filed January 11, 1915.

To all to 7mm t may concern.'

it known that l, Davie A. Fnnius, a citizen of the United States, residing at Ithaca, in the county of rfompl-ins and citate of N ew yorlr, hare invented a new and useful @hung-Clamp, of which the following is a speciiication rliis intention has reference to gluing clamps, and its object is to provide a clamp structure of practically universal applicability whereby a relatively large number of articles consisting of parts glued together may be clamped at one time in one structure, thereby avoiding the use of a large number of clamps which have heretofore been found ecessary for a lilre purpose.

ldlhere two pieces of wood, say, two boards or strips, are to be glued together edge to edge, it is customary to employ two or three or more clamps to hold these boards in close edge to edge union until the glue has se. Where a large Variety. of pieces are glued together the necessary stock of clamps is correspondingly large and the work necessarily taires up a large amount of space.

lWith the present invention there is provided a single structure capable of receiving and holding a large amount of work, whereby a great variety of gluing may be proceeded with at the same time and occupy a. minimum of space during the period of rest when the parts are clamped firmly t0- gether and so remain until the glue has set. lh/loreorer, the present invention provides a skeleton frame structure capable of being dismantled to occupy a minimum of space when not in use, and which may be set up to accommodate various lengths, widths, and thicknesses of material and to hold such material with the parts in firm union during the gluing operation.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification, with the further understanding that while the drawings show a practical form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modiied so long as such changes and modifications mark no material departure from the salient features of the invention.

tive view of the gluing clamp frame ready for the application of the material to be glued, the spacing strips and other parts being omitted. Fig. 2 is a longitudinal vertical section with some parts in elevation showing the gluing clamp structure with some work in position. Fig. 3 is a top plan view of one end of the structure of Fig. 2, said end being the left hand cnd as viewed in Fig. 2. Fig. 4; is a section on the line etof Fig. 3. Fig. 5 is a bottom plan View of one of the sills and some of the cross strips of the clamp. Fig. G is a perspective view of one of the spacing strips or bars.

VReferring to the drawings there is shown a basic frame consisting of longitudinal sills or beams l joined by a sui'licient number of cross strips 2. Each beam or sill l on the edge facing the other beam or sill has a longitudinal groove 8 therealong. Adapted to extend from one beam to the other and movable lengthwise therealong are other cross strips 4f each provided near :i

each end with an angle clip 5 made fast to the strip 4 and shaped to enter a correspond ing one of the grooves 3 so that the strips 4: may be moved lengthwise of the beams l without liability of escape therefrom. Each strip lis provided with a longitudinal series of holes or perforations 5a and each perf foration 5 is entered by a passage 6 extending from one edge of the strip 1l. Adapted to any one of the passages 5 are posts 7 havf ing perforations 8, 9, at the respective ends for theY reception of pins 10 each having a manipulating head ll for convenience oil handling. These pins need not of necessity be specially formed pins, since certain sizes of wire nails are well adapted for the purpose. Each post 7 is preferably made of metal pipe but may, of course, be made solid, or .of other material than metal, and while it is customary to form the beams, bars and strips of the clamping frame of wood, it will be understood that they may be made of metal, and especially structural metal. However, as it is quite usual. to make structures either of wood or of appropriate angle metal, and sometimes sheet metal stiffened by appropriate flanges, it is deemed unnecessary to illustrate the various ways of constructing the frame and the illustration is therefore continedto a wooden frame with tubular posts. Each strip fi is usually provided with atleast two posts 7 lat the opposite ends, which posts, however, `may be.,

slaced at any points aleng the strips perl mitted by the holes rihe ends ot the strips rest upon the top faces of the beams 'there is lodged a lon'oitudinallv dis nosed er n f l beam 13 unich may be, though it is not necessarily longer than the beams 1, andthis beam 13 'is siidable both lengthwise and crosswise of the basic frame made upof the beams 1 and cross strips 2, and is confined to the cross strips 2 supporting it by the overriding cross strips el. Erected on the beam '13 at the ends thereof are posts 14 connected together at the upper ends by another beam The posts 14: are connected to the beam .13 by pins 10 and the beam 15 is connected V'to the post 14 at the upper ends thereof by :pins l0, the posts 14- being appropriately perforated for the purpose. rlfhere are also provided an appropriate number or" spacing strips or bars 16 having a series of passages vor perforations 17 corresponding to the perforations 5*"- of the strips et. Some of the spacing .bars 1G are of the same length as the strips l and in such case may be threaded upon the posts 7 when the passages 17 will match the passages 5a. There arevalso provided other spacing bars 1(3L which may be ot shorter length than the bars 16, but have similar' perforations 17 similarly spaced apart. There arealso provided other posts 18 of suitable lengths adapted to traverse any of the passages 5 or 17. In addition to the partsv already named wedges 19 are provided for a purpose which will presently appear.

The gluing' clamp structure is made of a size to accommodate the largestpiece of work for which it is probable the clamp will be used, while the parts provided for use in connection with a clamp willreadily take smaller work. As examples of the class of Work for which the clampv is adapted, there isshown a panel door 20 andvarious groupings 21, 22 andv 23 of boards or strips which it is assumedV are glued together .edge to edge. ln the case or' the door 20 it is necessary to bring pressure thereupon both laterally and longitudinally thereof. As the door in the particular structure shown approximates 1n size the largest article for which the clamp is designed, it isrlaid upon the strips l within the space defined by the posts 7 and 1d. Now, wedges 19 are Vdriven between one edge of the door frame and the posts 7 adjacentto said edge, thus clamping the door frame between the several posts 7 Also, a wedge' is driven between one of the posts lil and the corresponding end of the door, thus clamping the other end of the against which Y door vagainst the other post 1-1. Before the lSimilzuly other spacing strips 1G and glued groups 22 are piled upon the parts already in place. lt may be that a shorter length 23 of glued strips is ready tor clamping, whereupon but two oi? the groups ot posts 7 adjacent one to the other need be provided with spacing strips 1G in addition to those already in place, and if the width ot the group or glued strips be less than the full width of the structure then shorter ones of the spacing strips represented at 1Gn may be applied. Such strips, however, will not reach from one post 7 to the other carried by the same strip el, and hence intermediate shorter posts 18 are inserted in appropriate holes in the spaced strips 16 and traverse corresponding holes in the strip or strips 1t, thus providing intermediate posts wedges 19 may be driven to force the strips engaged by them against the primary posts 7. ln this manner a pile of articles being glued together may be included in the ene frame with each article spaced from the other by spacing strips 1G, and where the pile does not reach to the top Ot' the posts 7 braces Q1 are applied to the then topmost strips 1G and 1G, being nailed thereto by nails 2,5, while the other ends of the braces 2llodge under respective pins 10. The purpose of the strips '24; is to prevent buckling of the topmost spacing bars 1G or 1G, and these braces also prevent buckling of the lower strips 1G. ',lhe wedges are driven between the parts to be glued and the respective posts, so that the parts to be glued are brought into close engagement to there remain so long as may be needed to effect the gluing together of the parts.

lVith the present invention it is 'possible to assemble and hold in clamped relation a large number of pieces being glued together while the whole assembled structure takes relatively small space and eliminates wholly the great multiplicity of clamps heretofore required in shops or other places where a large amount of gluing is being constantly performed. lrlcreorer, the gluing' clamp is susceptible of manufacture at low cost and in practice is found equally ctlicient with and oftentimes more eilicient than the customary forms of clamps employed in wood working.

The clamp of the present invention has the advantage that it permits the use of wedges which not only constitute an extremely simple form of pressure rmeans, but provides elongated bearing surfaces upon the work, thus avoiding the liability of dentlng or otherwise marring the work. The clamp structure also has the advantage of providing for the gluing of both wide and narrow groups of strips or'boards at the saine time. rlhis is brought aboutby the use of supplemental posts 18v and either shorter perforated strips 1G or full length perforated strips ll, and 16, since the supplemental posts may be erected anywhere along the strips between the end posts 7 carried by the strips ei or 16 or both. Since `the additional or supplemental beams 13 and 15 for bringing end pressure to bear upon some structures may be placed anywhere with respect to the width of the gluing frame, it is quite possible to use twoor more of such end pressure means, although in most instances a single end pressure structure will be sufficient, and, moreover, need not interfere in any manner with the use of the remaining portion of the structure for clamping smaller groupings during the gluing operation.
